Mechanism Analysis of Dynamic Compaction based on Large Deformation
In the mechanism analysis of foundation consolidation by using dynamic compaction, many kinds of non-linear conditions exist. This paper adopts large deformation on the relationship between strain and displacement. Non-linear governing equation of soil, based on finite element method, is established. Iterative calculation form is raised. Finally, non-linear numerical analysis is done to a calcu...
متن کاملOn the Corotational Beam Element Formulation in Large Deformation Analysis
This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
متن کاملNonlinear Large Deformation Analysis of Rubber Bumpers in Automotive Suspensions
In this article, rubber bumpers of Double - Wishbone suspension system have been modeled and analyzed. The objective of the present work is to predict the performance of these products during deformation, represent an optimum method to design, obtain stiffness characteristic curves and utilize the results in the automotive suspension dynamic analysis. These parts are nonlinear and exhibit large...
متن کاملConstitutive Analysis of Large Elasto- Plastic Deformation Based on the Multiplicative Decomposition of Deformation Gradient
Abstract-By using Lee’s (1969. 1. Appf. hfech. 36, l-6) multiplicative decomposition of the deformation gradient into its elastic and plastic part of Hill and Rice’s (1973. SlAbf J. Appf. Math. U, 44S-461) constitutive framework. explicit and consistent constitutive analysis of large clastoplastic deformation is given. Both isotropic and anisotropic material behaviour is considered. so that som...
متن کاملDynamic Recrystallization by Necklace Mechanism During Hot Deformation of 316 Stainless Steel
The aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (DRX). The material used is 316 stainless steel. In order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °C with strain rates of 0.01-1s-1. The result shows that at the tempera...
